To all lwhom t may concern.: Y Y

Be it known that I', ORsoNB. CLARK, a citizen of the United States, residing 'at Sherburne, in thecountyy of 4Chenango, State of New York, have invented a newA and useful Improvement in Dish-Washing Machines, of which the following is a specication.

My invention relates to that class oftdish washing machines which include a receptacle in which` the dishes are disposed, and means for positively pro'ecting the water upwardly in said recep a'cle; toward and about the dishes held therein.

In accordance with my'invention, revoluble blades are providedfor directing the water upwardly about the dishes and one of the objects of my invention is to provide an improved form of blade which will perform this function in an elicient and effective manner. p

` My invention will be more fully described inconnection with the accompanying drawings and more particularly pointed out and ascertained inand bythe appended claims.

In the drawings z-Figure l illustrates one form v of my invention in a perspective view with part broken away and part in section. Fig. 2 illustrates a modified form of my invention in vertical section. Fig. 3 is a sectional view taken on the line 3 3 lof Fig. 2. Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2. Fig. 5 is a sectional view taken on the line 5-5 of Fig. y2.

Like characters of reference designate similar parts throughout the different figures ofthe drawing.

As illustrated, and referring more espe- -cially to Fig. 1,-a `receptacle is designated` at 11 and is provided with a suitable rev movable top 13. rIhe receptacle 11 is -preferably cylindrical in form and may be provided with a flat bottom wall 20, and if desired, may be supported at an elevation from the'floor by suitable supporting legs 12. An outlet 14 may be provided to empty the receptacle when it is desired to refill' the same with clean water.

kI provide means for suspending the dishes inthe freceptacle, above the bottom thereof, and said means may consist ofacylindrical rack 10, of reticl'lated formation, adapted vto be supported on legs 18 engaging th, `bOttom wall 20. The rack 10 may be provided with transversely disposed bars 21 between which the dishes may be disposed shaft 2 and'5 so as to be held in a substantially vertical position in the rack.

Blades 4 are revolubly mounted upon a ververtically disposed shaft 2, mounted near its upper end upon a suitable bearing 3 and being supported at its lower end by a suitable bearin 15. A gear 5 is secured to the meshes with a gear 6 mounted upon a shaft 8.y The shaft8 is horizontally disposed and is mounted in pendent hanger bearings 16 and 17 and is provided with a crank`9`on its outer end, by means of which blade t may be operated.

In the form shown in Fig. 2, the blade op- `erating shaft' 19 extends upwardly from the bottom to the top 22 of the receptacle 23. The top`22 is in the form of a cover and may be removed and therefore the up-` per end o f the shaft 19 is removably but non-revolubly connected with gear 5 and the bearing 241. Gear 5 meshes with a gear 6 mounted upon a shaft 8. Shaft 8 is mounted on bearings 16 and 17', secured to the cover 22. An operating crank 9 is secured to the shaft 8.

Next referring to the blades 4, and more same are formed integral with a hub 25, mounted on shaft 2, and project radially outwardly from the hub 25 toward the periphery of the receptacle 11. In the form shown two blades 4 are illustrated but'I do not wish to be limited to the precise con struction shown 'in this respect.

- It will be seen by reference to Fig. 1 that with respect to the direction of rotation, and with respect to the vertical. It will be seen by reference to Fig. 1 that the vertical por- -inclined portions 27 so that both blades describe a'continuous curve, the upper margins 29 being rearwardly disposed with respect direction of rotation.

especially to Fig. 1, it will be seen that the portions 27 areinclined slightly. rearwardly' to the lower margins 30, withy respect to theV the latter is mounted at its upper end in tions 26 and 28 gradually merge into the 4 It will be readily understood that in rota-- tion, the blades tend to collect the water rearwardly with respect to rotation of the blades, and between the outer sections 2S and the inner sections 26 in a direction toward the intermediate curved sections 27. With the flow concentrated toward the interniediate sections 27, and with the latter inclined rearwardly, itwill be readily seen' that the action of the blades tends to direct the water upwardly intov the rack 11 and about the dishes contained therein. By. reason of this construction the blades do not merely act as water agitators or splashers but positively directthe water upwardly into the rack 10. By disposing the inclined intermediate portions 27 between the center and thepperiphery of the receptacle 11, I

` obtain a continuous upward flow into the dish rack in a circular zone between the centerv and the periphery of the rack. The re sulting downwardilow will necessarily be through the central zone and the peripheral zone, at opposite sidesof the upward flow caused by the intermediate portions 27.'

It is desirable. to fill the receptacle to a point slightly above the'blades 4, in order to getthe best results.

' While I have herein shown and described specific forms of my invention, I do not wish to be limitedl thereto except for such a free collecting gportion extending forlimt-ations as the claims may import.

I claimz- Y 1. A dish washing machine comprising in combination, a receptacle having e: circular' flat bottom wall, a dishrack disposed. in'
